[WORKAROUND] Avoid unloading dynamic libraries for dpcpp kernels.

[kris-rowe]

Description

• Dynamically loaded device code is effectively a shared resource managed by the sycl runtime.
• Unloading the dynamic library for our kernels can corrupt objects owned by the sycl implementation (e.g., kernel bundles), leading to runtime errors.
• Avoid calling dlclose as a temporary workaround until issues related to dynamically loaded device code are resolved by the sycl spec and/or implementers. (See discussion here)
